Duct Underground Armored Cable GYTS

　　The Stranded Loose Tube Armored Fiber Optic Cable GYTS is a versatile outdoor fiber optic cable designed for a wide range of applications. It features a stranded loose tube design and is armored to provide excellent mechanical protection and durability. This cable is commonly used in long-distance communication networks, including aerial, duct, and direct burial installations. The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The PSP is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a PE sheath.
